Abstract

A pixel may include a light emitting element (OLED), a first transistor (M1), a second transistor (M2), a storage capacitor (Cst), and a third transistor (M3). The first transistor may be configured to transfer a data signal to a data line (Dm) when a scan signal is supplied to a scan line (Sn). The second transistor may be configured to supply a predetermined electric current from a first power supply (ELVDD) to a second power supply (Vref) through the light emitting element. The storage capacitor may be charged with a voltage corresponding to the data signal, one terminal being coupled to a gate electrode of the first transistor, and another terminal being coupled to the organic light emitting diode. The third transistor may supply a voltage of a reference power supply to the light emitting element when the scan signal is supplied to the scan line.
